I'm 6-1, but all my height is in my upper body. With the seat almost fully back and reclined so the seat hits the bulkhead, I have <1" headroom. And to exacerbate the situation, I am somewhat broad of beam, so the left driver's bolster is taking a beating.

But once in I'm quite comfortable. But if I gain 10 pounds, I am truely hosed. And come winter I know I will not be able to get comfortable with my lined leather coat on. But that's what the heater is for.
